You can use the MinGW-w64 compiler to build MEX files, a MATLAB^® interface to a C++ library, and standalone MATLAB engine and MAT-file applications. For more information, see 'MATLAB Support for MinGW-w64 C/C++ Compiler'.

Choose an installation directory. To avoid dramas, choose a folder without spaces in the path. Something like C: MinGW-w64 x8664-8.1.0-win32-seh is best. Sudo apt-get install mingw-w64. Which will install mingw-w64 and any other packages on which it depends. Package: mingw-w64: Version: 5.0.2-2: Maintainer: Stephen Kitt: Description: Development environment targeting 32- and 64-bit Windows 64-bit (x86 and x64) Windows applications using the Windows API and the GNU Compiler.

Install MinGW-w64 Compiler. To install the compiler, use the Add-Ons menu. On the MATLAB Home tab, in the Environment section, click Add-Ons Get Add-Ons. Search for MinGW or select from Features. Building yprime.c Example. You can test the MinGW ® compiler.

Install MinGW-w64 Compiler

To install the compiler, use the Add-Ons menu.

On the MATLAB Home tab, in the Environment section, click Add-Ons > Get Add-Ons.
Search for MinGW or select from Features.

Building `yprime.c` Example

You can test the MinGW^® compiler by building the yprime.c example. Copy the source file to a writable folder.

If you only have the MinGW compiler installed on your system, the mex command automatically chooses MinGW. Go to the next step. However, if you have multiple C or C++ compilers, use mex -setup to choose MinGW.

Build the MEX file.

MATLAB displays a “Building with” message showing what compiler was used to build the MEX file.

Run the function.

MinGW Installation Folder Cannot Contain Space

Do not install MinGW in a location with spaces in the path name. For example, do not use:

Instead, use:

Updating MEX Files to Use MinGW Compiler

If you have MEX source files built with a different MATLAB-supported compiler, you might need to modify the code to build with the MinGW compiler. For example:

Library (.lib) files generated by Microsoft^® Visual Studio^® are not compatible with MinGW.
Object cleanup is not possible when an exception is thrown using the mexErrMsgIdAndTxt function from C++ MEX files, resulting in memory leak.
An uncaught exception in C++ MEX files compiled with MinGW causes MATLAB to crash.
MEX files with variables containing large amounts of data cannot be compiled, as the compiler runs out of memory.

How to Install Cygwin

Cygwin (pronounced as SIG-win) = GNU + Cygnus + Windows. The mother site for Cygwin is www.cygwin.com.

According to the developers, 'Cygwin is a Open-source Linux-like environment for Windows. It consists of two parts:

A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing substantial Linux API functionality.
A collection of tools which provide Linux look and feel.'

To install Cygwin:

Step 1: Download Setup

Goto Cygwin mother site @ https://www.cygwin.com ⇒ Click 'Install Cygwin' ⇒ Download the setup program 'setup-x86_64.exe' (64-bit Windows) or 'setup-x86.exe' (32-bit Windows).

Step 2: Run Setup to Select, Download & Install Cygwin Packages

Run 'setup-x86_64.exe' ⇒ Install from Internet ⇒ select a directory (avoid installing in 'Program Files' because of that 'blank' character) ⇒ choose 'Local Package Directory' which saves the downloaded installation files ⇒ Direct Connection ⇒ choose a download mirror site.

Select the packages that you wish to install.

Important: For programmers, you certainly need to open the 'Devel' (Development) category and select 'gcc', 'g++', 'gdb', 'make', and others, which are not part of the default selection.

Browse thru all the categories. Complete the installation process. You can always re-run 'setup' to install additional packages later.

Step 3: Setup PATH

Include the Cygwin Binary directory (bin) in the PATH environment variable.

Suppose that your Cygwin is installed in directory 'c:cygwin'. From 'Control Panel' ⇒ (Optional) System and Security ⇒ System ⇒ Advanced System Settings ⇒ 'Advanced' tab ⇒ Environment Variables ⇒ System Variables ⇒ Select variable named 'PATH' ⇒ Edit ⇒ Add 'c:cygwinbin;' in front of the existing PATH entry. Note that the semi-colon serves as the directory separator to separate Cygwin from the rest of directory paths.

Step 4: Verify Cygwin

Installing Mingw W64 Windows 7

Start the Cygwin Command shell (bash

or sh) by running 'cygwin.bat'. You shall see the command prompt '$'. You may need to create the users' group and password files by running the following commands:

Try out some Unix commands (you need to read a Unix book - there is no short-cut in learning), e.g.,

Need help? Try:

On bash shell, after setting the directory to the the 'root' (via 'cd /'), you could find a directory called 'cygdrive' (via 'ls' or 'dir'), where all the hard disks are mounted. 'cd cygdrive' and 'ls' lists all the hard disks, e.g., 'c', 'd', etc.

You may mount your C drive ('c:') as '/c' instead of the default '/cygdrive/c' via this command:

You could invoke the Cygwin programs and utilities via the Windows' Command Prompt ('cmd.exe') instead of bash shell (provided the PATH is set properly), e.g.,

How to install MinGW

[To Check] Is MinGW obsoleted by MinGW-W64, which supports both 32-bit and 64-bit Windows?

MinGW (short for 'Minimalist GNU for Windows'), is a minimalist (i.e., small but fewer features compared with cygwin) development environment for native Microsoft Windows applications, in particular:

A port of the GNU Compiler Collection (GCC), including C, C++, ADA and Fortran compilers;
GNU Binutils for Windows (assembler, linker, archive manager).
MSYS (short for 'Minimal SYStem'), is a bash Shell command line interpreter.

To install MinGW:

Installing Mingw W64 Download

Goto MinGW mother site at http://www.mingw.org/ ⇒ Downloads ⇒ Installer ⇒ click on 'mingw-get-inst' link to download the installer.
Run the downloaded installer.
1. Set the installation directory. (Try to use a directory name without spaces, e.g., 'd:myprojectmingw'. Try not to install under 'Program Files' or 'Desktop'.)
2. In MinGW Installation Manager, select 'Installation' ⇒ 'Update Catalogue' ⇒ Select all packages in 'Basic Setup' ⇒ continue.
Setup environment variable PATH to include '<MINGW_HOME>/bin' where <MINGW_HOME> is the MinGW installed directory that you have chosen in the previous step.
Verify the GCC installation by listing the version of gcc,g++ and gdb:

How to install MinGW-w64

MinGW-w64 is a fork of MinGW to support 64-bit Windows (as well as the 32-bit windows). The mother site is http://mingw-w64.org/doku.php.

You can install MinGW-W64 under 'Cygwin' by selecting these packages (under 'Devel' category):

mingw64-x86_64-gcc-core: 64-bit C compiler for native 64-bit Windows. The executable is 'x86_64-w64-mingw32-gcc'.
mingw64-x86_64-gcc-g++: 64-bit C++ compiler for native 64-bit Windows. The executable is 'x86_64-w64-mingw32-g++'.
mingw64-i686-gcc-core: 64-bit C compiler for native 32-bit Windows. The executable is 'i686-w64-mingw32-gcc'.
mingw64-i686-gcc-g++: 64-bit C++ compiler for native 32-bit Windows. The executable is 'i686-w64-mingw32-g++'.

To check the versions:

You can also install MinGW-W64 stand-alone by downloading and run the installer.
